It is too early to ascertain the method of attack and the range of implications of this attack on the Kerch Bridge. It is certainly a punch in the face for Putin on his birthday. A couple of thoughts however in this short (for me) thread. 1/9 🧵
2/ First dropping a bridge span like this would take a lot of ‘bang’ (explosives) and good demolition design. As a sapper, we plan these kind of things all the time. The hardest bridges to drop are reinforced concrete like this. (Image: @RALee85) Image
3/ The amount of explosive required would be more than a few SF personnel could carry. A few trucks, or missiles / bombs would do the trick, if aimed at the right points of the bridge span.
4/ Second, the Ukrainians so far have been excellent at operational design and shaping operations in advance of their advances. This could be part of their design for taking back Crimea in the short term - or part of a deception operation to distract from other areas.
5/ Either way, it presents the Russians with a significant problem. It doesn’t stop resupply to Crimea (there are boats and the route through Melitopol), but it makes holding Melitopol even more important for the Russians. (Image: @TheStudyofWar) Image
6/ This would be the point in a class that the instructor would ask “so, what do we think the next operational objective for the Ukrainians might be?” Because of this, we may see Russian redeployments in the south, which will unveil other weaknesses & opportunities for #Ukraine.
7/ A third and final point: this is a massive influence operation win for Ukraine. Even if they didn’t do it, it is a demonstration to Russians, and the rest of the world, that Russia’s military cannot protect any of the provinces it recently annexed.
8/ And if we were impressed by the outflow of Russians after the recent naval aviation base attack, the rush to leave Crimea will be probably be even greater now. Lack of confidence in Putin and his military will grow.
9/ I am sure we will learn more details in the coming hours and days. But this ‘smoking incident’ is sure to be linked to other events in Ukraine’s overall military strategy. A bad month for Russia just keeps getting worse. Good. End. Image

100s of drones downed over Moscow & a major oil refinery ablaze for the 2nd time in a week. Ukraine's largest strike on Moscow leads this week's update. 1/5 Image
2/ The deep-strike campaign is now a central element of Ukraine's war to defend itself and secure a just peace. By Kyiv's own accounting it has knocked out roughly a tenth of Russia's refining capacity. On the ground, Russia's spring offensive in Donetsk looks close to culminating.
3/ In the Pacific, INDOPACOM reverts to Pacific Command as Beijing presses around Taiwan, the Philippines and Japan.

Ukraine has just struck a Russian defence plant with its new long-range FP-5 missiles and damaged a key bridge to Crimea. Things keep getting worse for Putin and Gerasimov. My Part 2 assessment of Russia's losing war, and how Putin might reverse things. 1/5 🧵 Image
2/ Russia is losing its war on Ukraine. But a losing trajectory is not a settled outcome. Part 2 of Losing on Every Dimension examines the five "reversal conditions" that could still rescue Putin, and what the West must do to lock in his defeat.
3/ The most revealing point about these five reversal conditions. With one exception, none lies within Russia's own control: a US settlement, the oil price, China's treasury, North Korean manpower, and Western fatigue. Russia's escape from defeat depends on the decisions of others.

For the first time since the invasion, Russia is losing more troops than it can recruit. Net territorial movement over the past three months has favoured Ukraine. Part 1 of my new assessment, I explore how Russia is "Losing on Every Dimension" - military, cognitive, moral, industrial and economic. 1/7 🧵Image
2/ MILITARY. In 2025 Russia paid roughly 200 casualties per square mile taken. In the first five months of 2026, with a net gain of 17 square miles, it paid over 9,600 per square mile. The meat grinder is grinding through Russian men faster than Russia can produce them. Tactical operations are now unified with mid-range and long-range strikes.
3/ COGNITIVE. Russia's narratives are decoupling from a battlefield made visible by open-source reporting. When Putin has to ask Ukrainian permission to hold parades, and cannot hold an international forum without a Ukrainian attack, his narrative about inevitable war crashes.

Our darker angels have returned. For a decade, influential scholars argued that major war was on an irreversible decline. Pinker's 'Better Angels' thesis became almost orthodoxy in parts of the security studies world. But, as @lawdavf has written, war has a future. 1/4 🧵 Image
2/ Fast forward to 2024. PRIO records 61 state-based conflicts — the highest since World War II. 129,000 battle deaths. The fourth most violent year since the Cold War. The 2024 data from SIPRI and PRIO is unambiguous: a historic peak in state-based conflicts, the fourth most violent year since the Cold War, and a Russo-Ukrainian war that has now consumed an estimated 500,000 lives.
3/ The analytical failure wasn't just academic. Governments that accepted the 'war is fading' narrative underinvested in defence, deterrence and industrial capacity. Ukraine paid some of the price. But most Western nations are still underinvested in force structure, defence industry, war stocks and most importantly, national will to resist authoritarian aggression.

China fields a military where 70-80% of soldiers are only children. Every battlefield death risks extinguishing a family line. This demographic reality shapes Xi's strategic calculus in ways Western analysis should pay more attention to. My new piece explores this. 1/5 🧵mickryan.substack.com/p/one-child-on…Image
2/ China's one-child policy ended in 2015. Its military consequences are only beginning. By 2015, ~70% of PLA soldiers and 80% of combat troops came from one-child households. There is almost no historical precedent for a major military force comprised almost entirely of only children.
3/ The research is sobering. Only children are measurably less trusting, less resilient, less risk-tolerant, and less competitive than those with siblings. These are not ideal traits for combat. They are increasingly the defining traits of the PLA's human capital.

Some initial thoughts on the new Australian National Defence Strategy released today in Canberra. Overall, the focus and trajectory of Australia's defence strategy remains consistent with the 2024 version. There are some notable things worth highlighting. 1/15 🧵🇦🇺 Image
2/ The new NDS shifts more towards a true 'defence' strategy rather than just a 'military' strategy that was described in the 2024 version. There is stronger language around national civil preparedness, fuel security, and economic security. This is good. But these are also topics that should be in a National Security Strategy - if Australia had one!
3/ Spending. There is an uptick in spending. This is a positive. There is a claim that we might get 3% of GDP on defence at some point in the future. The reality is that because we are well short of this now, trying to fund both AUKUS and the ADF at the same time with current spending is challenging (nice word for not possible), and conventional military capabilities are degrading - and not modernising fast enough.
